Vanadium mainly exists in the form of carbide in elongation of P265GH and so on steel. Its main function is to refine the structure and grain size of steel and reduce the strength and toughness of steel. When the solid solution is dissolved at high temperature, the hardenability is increased; conversely, if it is in the form of carbide, the hardenability is reduced. Vanadium increases the tempering stability of quenched steel and produces secondary hardening effect. The vanadium content in steel, except high speed tool steel, is generally less than 0.5%.

Different form elongation of p265gh, room temperature and medium temperature boiler steel shall have those advantages:Higher room temperature strength;Good impact toughness and low notch sensitivity;As the drum and other parts require a lot of cold deformation during processing, room temperature and medium temperature boiler steel must have good aging toughness;Good processing technology and welding performance;Good macrostructure, etc.

The company has a solid economic foundation, a strong network of relationships, complete technology and staffing. With my country’s entry into the WTO, the import and export trade is increasing day by day. In order to further meet the needs of elongation of p265gh traders and importers and exporters, our company carefully builds for merchants One-stop service from door to door. We have a complete import and export service system in Mainland China, and elongation of p265gh have established close cooperative relations with many shipping companies and airlines.

Both the cross rolling method and the extrusion method must first heat the tube blank or ingot, and the steel tube produced is called hot rolling tube. Steel pipes produced by hot working can sometimes be cold worked as required. There are two methods of cold working: one is cold drawing, that is, drawing the elongation of p265gh steel pipe through the drawing die to make the steel pipe gradually thin and elongate; the other is cold rolling, which is the method of applying the hot rolling mill invented by the menesmann brothers to cold working. The cold working of elongation of p265gh seamless steel pipe can improve the size accuracy and finish of steel pipe, and improve the mechanical properties of materials.
